Again, a microprocessor 3 is embedded in the physical structure of the cassette 24. Alternatively, the microprocessor 3 may be located on the small side surface of the cassette 24. Instead of a CD/CD-ROM as shown in figure 1 or a cassette as shown in figure 3, any other known type of data carrier, such as floppy disk, may be applied to carry out the present invention.
  • the processor unit 5 embedded in the data carrier 1 is programmed to control read and/or write access of the processor 8 to the data carrier memory area 2.

  • the one or more keys are, preferably, unique to the data carrier and may be simply stored in memory 7 of the microprocessor 3 or be calculated by the processor unit 5, as will be explained hereinafter. Below, for the sake of simplicity of the description, it will be assumed that only one key is used.
  • At least a portion of the data in memory area 2 is stored after being encrypted by the key.
  • the key is directly stored in memory 7 of the microprocessor 3.
  • the processor unit 5 may be ananged to calculate the conect key based on one or more other (master) keys in memory 7 using key related data retrieved from memory area 2 on the data carrier 1. With reference to figure 4, such key related data will be read from the memory area 2 by processor 8 from the computer arrangement 11, preferably, without using any additional authorization mechanism, and then be transferred to the processor unit 5 through the communication interface 4.
  • the encryption algorithms used to conceal data to be protected on the data carrier 1 can be selected to use very long keys, like in one-time pad calculations which require keys of the same length as the protected data.
  • the processor 8 of the computer anangement 11 When the processor 8 of the computer anangement 11 is instructed by a user, through its input means 20, 22, to read protected (encrypted) data from data carrier 1, it will request the processor unit 5 to generate the correct key.
  • the processor unit 5 will send its key from memory 7 or calculate the correct key based on the key related data as indicated above and send the key to the processor 8.
  • the processor 8 will receive this key.
  • the processor 8 reads data from the memory area 2 of data carrier 1, step 42.
  • the processor 8 will use the key to decrypt data read from the data carrier 1 and store the decrypted data in its memory 14. Instructions as to how to communicate with the data carrier 1 may be loaded from the data carrier 1 to the processor 8 in any way known to the person skilled in the art, e.g., by loading an execute file from data carrier 1 to processor 8.
  • the generation of the key by the processor unit 5 will be dependent on whether or not one or more conditions have been met. This is further explained in figure 6.
  • One such condition may be the time period that the data in the data carrier 1 may be read and decrypted after a predetermined date loaded in memory 7 of the microprocessor 3.
  • the data may e.g. be a demonstration computer program which may be used during three months after which decryption will automatically be blocked.
  • Another condition may be the maximum number of times the data may be read from data carrier 1 and decrypted by processor 8 or any other processor external to data carrier 1.
  • the microprocessor 3 may store such a maximum number and check whether the number of times it is requested by a computer anangement to provide the key exceeds that maximum number. For instance, in many cases an end-user is allowed to read and decrypt the data twice, i.e., once for regular purposes and once for back up. In such cases, the maximum number equals 2.
  • step 50 for checking the condition to be met the computer arrangement 11 and the data canier 1 start communicating in step 50.
  • the condition is preferably checked by processor unit 5 of the data carrier 1, step 52. Only if the condition is met the processor unit 5 will generate the required key and send it to the processor 8 of the computer arrangement 11, step 54.
  • Protection may further be enhanced by introducing an authentication mechanism of the user. Then, only when the user proves his/her authenticity to the processor unit 5 the latter will provide the conect key. To that end, passwords or user codes input by the user through one of the input means 20, 22 can effectively be used. Such a pass word or user code must then correspond to a password or user code stored in memory 7.
  • a password acceptance algorithm based on additional authentication data stored in the data canier 1 may be used.
  • Such authentication data may be read by processor 8 from the data carrier 1 and be transferred to the microprocessor 3 (see figure 4).
  • a password input by a user may, e.g., be checked by the processor unit 5 as being valid upon checking whether or not it belongs to a dictionary of acceptable words stored as such authentication data in the data carrier 1 possibly complemented with rules for combining them, the rules being stored as an authentication key in memory 7.
  • User identification may also be canied out by using the smart card reader 13 and smart card 15 that belongs to a user who knows a password associated with the smart card 15.
  • the smart card reader 13 may be arranged to read smart card 15 provided with an electronic purse facility and the processor unit 5 may be ananged to allow decryption of data from the data canier 1 only when a predetermined amount of money has been paid through the electronic purse.
  • a payment facility through the Internet is another option for paying in advance of any next decryption step.
  • the protection mechanism illustrated above may be expanded to providing different sets of keys for different sets of data on the data carrier.
  • the copy of the data to be protected and loaded in the computer memory 14 may be provided with a digital watermark calculated by the microprocessor 8 during the process of loading the data into the computer 11.
  • the calculation algorithm used by the processor 8 to provide the watermark is derived from the data carrier 1. Alternatively, either a part of or the entire watermark is calculated by processor unit 5 and sent to the processor 8.
  • the watermark may include the time of loading, user identity information or any other information to uniquely identify a stored copy of the loaded data.
  • the watermark may use data elements of the data itself such that the data itself will at least be partly damaged if somebody tries to remove the watermark.
  • the watermark serves as an identifier to locate the source of illegal copies of the data.
  • the processor 8 is shown to be one block. However, if preferred, the processor 8 may be implemented as several sub-processors communicating with one another each dedicated to perform a predetermined task. Preferably, the processor 8 is (or the sub- processors are) implemented as a computer with suitable software. However, if desired, it (or they) may be implemented as dedicated digital circuits.
  • the software running on the processor unit 5 of the data carrier 1 and on the processor 8 of the computer arrangement 11 may, prior to loading, be stored on a data carrier like a CDROM or may be distributed through a telecommunication connection (for instance entirely or partly wireless) like the Internet.
